The purpose of this series is to:

  - Fix the "BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment"
    messages reported by Linus [1], Andy [2], and others.

  - Move arch-specific shadow ROM location knowledge, e.g.,
    0xC0000-0xDFFFF, from PCI core to arch code.

  - Fix the ia64 and MIPS Loongson 3 oddity of keeping virtual
    addresses in shadow ROM struct resource (resources should always
    contain *physical* addresses).

  - Remove now-unused IORESOURCE_ROM_COPY and IORESOURCE_ROM_BIOS_COPY
    flags.

This series is based on v4.5-rc1, and it's available on my
pci/resource git branch (along with a couple tiny unrelated patches)
at [3].

Bjorn Helgaas (12):
      PCI: Mark shadow copy of VGA ROM as IORESOURCE_PCI_FIXED
      PCI: Don't assign or reassign immutable resources
      PCI: Don't enable/disable ROM BAR if we're using a RAM shadow copy
      PCI: Set ROM shadow location in arch code, not in PCI core
      PCI: Clean up pci_map_rom() whitespace
      ia64/PCI: Use temporary struct resource * to avoid repetition
      ia64/PCI: Use ioremap() instead of open-coded equivalent
      ia64/PCI: Keep CPU physical (not virtual) addresses in shadow ROM resource
      MIPS: Loongson 3: Use temporary struct resource * to avoid repetition
      MIPS: Loongson 3: Keep CPU physical (not virtual) addresses in shadow ROM resource
      PCI: Remove unused IORESOURCE_ROM_COPY and IORESOURCE_ROM_BIOS_COPY
      PCI: Simplify sysfs ROM cleanup
